What am I looking at here. Why would this be used as an example of a two stroke? It looks like a two stroke twingle.
Again why this as an example, seems misleading for beginners.
Thanks for any insight.

I see your point. Would have been better to use a single cylinder for both examples.

And maybe show the valves for the 4-stroke and the porting and fuel air mixture flow for the 2-stroke.

A little too basic for my liking!

Never seen anything like that. That is so cool, definitely would be a really confusing example for a beginner though.

See that WAY too often, explanations that are more like exconfusions.
